To test this hypothesis, the researcher randomly assigns a sample of participants to one of two groups: those who will use the app over a defined period, and those who engage in a control task.

An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques Internal validity gives you information about the rigor of the research study design and conduct of the study. It helps you to decide if you can believe the results of that particular study. There are multiple threats to internal validity including history, instrumentation, maturation, mortality/attrition, selection bias, regression, and testing.
